Why Chronic Kidney Disease(CKD) without symptoms ?
Since about 180 liters of
ultrafiltrate is formed in the kidneys, it is possible to pass normal quantity of urine inspite of the kidneys being chronically damaged . So even when 90% of kidneys are damaged, there can be a normal urine output.
Disease of the kidneys often does not produce urinary symptoms when chronic. The body also adapts when a disease is
chronic.
